Removing iso from wiiflow ?

Okay may seem a strange question and probably the reverse off what the majority off newbies ask ??!! but just wonder how you go about removing an iso from your HDD / wiiflow. I have a newer version off a game that I wish to replace with one that is on the drive already, easy enough to do ??

I came here with the same question. I knew that you could do it in wiiflow but the options were not there . I had the lock code on and the options don't show up until u enter the code to unlock the options. I felt like a fool.
